Search for Surrogate Marker(s) of Immunity Following Vaccination with Experimental Vaccine (Autoclaved Leishmania Major + Bacille Calmette-Guérin) in Human Volunteers

Description: Cutaneous leishmaniasis (CL) is usually a self-limiting lesion on the skin while visceral leishmaniasis is a progressive, systemic disease with high mortality even if treated. The problem associated with treatment and vector control justifies a search for an effective vaccine which seems to be the only practical means to control the disease. The aim of this study is to identify immunological surrogate marker(s) associated with protection against Leishmania infection. The results indicate that a… more

Neurophysiological and Behavioral Correlates of Language Processing and Hemispheric Specialization

Description: The purpose of this study was to examine language organization in the brain by using a series of three tasks concurrent with event-related potentials (ERPs) to investigate both hemispheric differences and interhemispheric reactions. Overall, the findings from this study support a relative rather than absolute hemispheric specialization for language processing. Despite an overall RVF (LH) advantage, both hemispheres were capable of performing the tasks and benefited from semantic priming.

Carson McCullers Beyond Southern Boundaries: Diagnosing "An American Malady"

Description: The loneliness theme of Carson McCullers' fiction falls into three divisions or levels. And because of her focus on the individual, her general theme of loneliness as it results from human isolation is universal.

In expressing her concept of isolation as a human condition, however, she presents loneliness as she believes it exists in her own culture, and, for this reason, her wor… more

Trust and Governance in Hybrid Relationships: An Investigation of Logistics Alliances

Description: Transaction cost economics (TCE) theorists traditionally have classified transactions between firms as governed by either market or hierarchy. By assessing characteristics of the transaction - asset specificity, uncertainty, and frequency - firms choose the governance form which minimizes transaction costs, the costs of administering the business deal. During the 1980s, however, TCE has found itself unable to explain the proliferation of strategic alliances. These hybrid relationships seek the … more
